yo, i have a similar thread open because i thought there is a problem with signalling server.
clean cache i done even. using also a ip and startet c2 as admin. start from website is the same problem.
but tab switches do not change the connection. don't understand what u mean.
host & client i have as log entry.
in my video u can see both games are still connectet.
also if the tab is in forground the pieces disappear, should not happen.
yes, in 2 windows it is ok.
p2p connection with same ip should not be a problem because ports are used for data transfer.
i still think its a bug because in last betas i not had this problem.
also because there was some optimizations for more speed.
I appreciate for your help.
ahh u remember me i want install chrome browser at my pc for testing.
edit: chrome show exact the same problem within tabs.
it belongs if the window get inactive for example at minimized.
